Product details

Robust 4WD Mini Monster Truck with Spektrum technology. Ball bearing equipped with metal gears. All-wheel drive with a 380 28T brushed motor. Independent wheel suspension with oil-filled shock absorbers. Body mount without clips. Spektrum SLT 2-in-1 receiver with 25A controller. Includes Spektrum SLT2 remote control, 2S 1400 mAh LiPo battery, and USB-C charger. RTR - Ready to Run. These models are ready to use right out of the box. You receive a complete package with a pre-assembled model, a compatible transmitter, a battery, and a charger. Due to its ease of use, this type is ideal for entering the world of model sports. Monster trucks are characterized by oversized tires, elaborate shock absorber systems, and good off-road capability. However, the high ground clearance also results in a high center of gravity. A brushed motor is particularly convincing due to its simple design and resulting ease of maintenance. Additionally, the brushed motor is significantly cheaper to purchase compared to a brushless motor. Difficulty level: Beginner. No special prior knowledge in model building is required for this product. The necessary materials for completion and operation are usually fully included in the delivery.
